Specification of Letters Patent.

Patented Feb. 8, 1916.

Application fit. February 10, 1915. Serial No. 7,318.

This inre'ntitm relates to eertain new and useful improremcnts in ground eonneetions for eleetrieal eonduetors. and pertains more partieularly t that type of ground eonnertion which is adaptable to eonueetion with the pipes of water or gas systemsemployed in.. .lwellin;!s and the like.

One of the. objects of the invention is to provide a device of this eharaeter whieh. owing to its adjustability is readily adaptable to pipes ot \'a/rious sizes.

further obje ttt of the intention is. to provide a derie which can be easily at tauhed to and de aehed from pipes.

further ob eet of the invention i-s to provide a deri e of the aborestated eharaeter whieh cap be not only cheaply manntact-tiredlittt also possesses minimum of parts. thusfaq'llitatiufl t ..embling.

Referring: t o the drawings: Figure l is 4 a perspeet-irefriew of the deriee in plaee n a pipe; l ifLi'L is a sectional view taken on the line of Fig f: Fig. i is :eseetional riew taken ,on the line i-3l of li 1 fl: and Fi l. -l; is a fat-e riew of the blank.

ltel'erriu more particularly to the drawinf!s. the fuuneral l designates a pipe employed injnsual gas or water systemswhieh .="pipes ran r in size.

'l he tittnieral i designates a strip of tlexibh; [Halt-rial such as copper. tin. or sheet iroh. oui end of whieh rolled orer upon the body portion as shown at x i. and teruiiuatd g in a free [lat end portion -l whieh lies in et u taet with the adjaeent part of the body as btqft seen at 5 in Fig. 2 for a purpose to lie hereinafter desrrilietl.

in proximity to the rolled over end l ol the blank. is formed a perforation while exit-ut'liu; from a point substantially midway of the ends of the. blank to the end opposit t the rolled orer end I is a plurality of perf rations (L T, S and lhe body portion "1 is provided with a reir'tt'oreiu nienilier ltl in the form of a l'ee tangnlar pieee (it still metal whieh is periorated and is rigidly secured to the part; 5

of the body with its perforation in register with the perforation 5.

Passing through the perforation? is a bolt 11 which has its head 1'2 in'contact. with the reinforcing member 10, and its free sere\\'threa(ted end 13 engaged by. a nut; 15. the bolt being adapted to pass through any of the openings-6. 7,8 or 9..

In use. the flexible metal band is bent to .stlt'l'ottlltl the pipe 1 as shown in Fig. 1,

whereupon the bolt 11 is inserted in the perforation 5. and its free end is passed through one. of the perforations G, 7, 8 or 9 according to the size of the pipe after which" the nut 13 is threadedonto the. end of the bolt ll. tightening of the nut 15 the body portion of the metal strip which engages the pipe is t'ansetl to eontorm to the shape or contour thereof and owing to the presence of rein- 1 toreing aueniber 10 the head 12 of the bot is prevented from injuring 0r tearing th blanlcf'l. and the latter is 'held stitt' and ri \\'hei;t reinforced by meinber lO Byrolling over the end 3 of theblanzt onto the body portion as shown at 4, it will be seen that'the derice not,only"pr0\jids a resilient clamp for thexecaidnctor irel30, but one whieh will readily itdapt itself to eonduetors' of ditterent diameters, sincei merely bending the part i toward or awlay from the part 5 small or large conduct, rs

ran be readily aeetiunnodated, and in addition the eye which receires conductor 20 atld which is formed by the. rolled over part} 3 ean be bent up or down as desired: r

it is to be particularly noted that the resent inreutioi; can be easily. and quickly applied to pipes of rarying diameters and that. the member ltl set-res to bend the metal into (lose engagement with the pipe upon tightening of the nut.

The. part 4 provides an edge which can be readily lifted s as to remove the conductorand to also enable eonducto'r of various sizes to be plaeed within tho eye.

\Vhat is elaimed is: J

.\s a new article of mannfactnre zt ground eonneetion for eleetrit" conductors eomposed of a flexible strip bentto haw i end porlions lie in superposed relation, no of the horizontal end portions being Slglrtly dc Ileeted downwardly and then roll dover to form a substantially eireular ,con uctor reeeiring eye, the free terminal/0f said end It will be thus seen that upon 1 end portions of" the strip thereon, said block providing an edge which "said free fiat wing, a reiatively narrow striplikeblock. of a length approximately equal to'the width of the strip rigidly secin'ed to said end portion of the latter at a point in we rdly from the free-side of the wing,'and

e bolt passed through said block and the and having a nut when the bolt is tightened causes the strip to bent at said eeige into engagement with the pipe, said block also serving as a reinforcement for said specified end portion of the strip carrying said Wing.

In testimony whereof I have hereunto set my hunt} in presence of two subscribing wit- 20 DAVID RGSEN.
